DAVID H. HOUSTON, OF HUNTER, NORTH DAKOTA.

EXTENSION-STOCK FOR FIREARMS.

SPECIFICATION forming part of Letters Patent No. 593,890, dated November 16, 1897.

Application filed January 22, 1895. Serial No. 535,795. (No model.)

To all whom it may concern:

Be it known that 1, DAVID H. HOUSTON, a citizen of the United Statesfresiding at Hunter, in the county of Cassv and State of North Dakota, have invented certain new and useful Improvements in Extension-Stock for Firearms, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

The object of my invention is to provide an improved extension-stock for firearms which shall be simple of construction, easily and effectively operated, and which when not in use may be closed up to occupy but little spacemore than the space occupied by the firearm.

1 My invention contemplates an improved skeleton stock for firearms arranged to slide in the butt of a pistol-grip stock, which skeleton stock can be quickly extended to meet the shoulder of the gunner.

Figure 1 is a side view of my improved firearm with the improved extension-stock closed up and dotted lines to show the position of the stock when extended. Fig. 2 is a central vertical sectional view of the pistol-grip stock and improved extension-stock, showing the extension-stock extended. Fig. 3 is an outer view of the concave side of the pistol-grip stock, showing a slot covered by a plate, through which slot the extension-stock slides, as seen in Fig. 2. Fig. 4. is a bottom view of the butt end of the pistol-grip stock, showing the butt-plate and part of the extension-stock.

In the drawings, in which similar letters of reference denote corresponding parts in all figures, A, Fig. 1, shows the extension-stock closed, which stock can be extended to the limit of the dotted line B and held in the extended position by the catch-bolt O in the hole D, Fig. 2. A spring E holds down the bolt O and causes it to snap into the hole D or D. In the pistol-grip stock there is a mortise G, through which passes from the bolt 0 a thumb-piece F, and upon which thumb-piece a slight pressure of the thumb upward raises the bolt 0 from the hole D or D, thus allowing the extension-stock to slide back and forward.

Having thus described my invention, what I claim is- The herein shown and described improvement in firearms, consisting of the pistol-butt having the channel or guide in the lower portion, the spring having one end secured to the inner wall of the pistol-butt, the catchbolt having a lateral projection on one side against which bears the free end of the spring, and a handle or finger-piece on the opposite side projecting out through the outer wall of the butt to be readily accessible to the finger, and the sliding skeleton stock. adjustable in the channel or guide of the butt and ha ring the notches or recesses to-reoeive the lower end of the catch-bolt for holding the stock at the proper adjustment,
